The emergence of cryptographically relevant quantum computers poses a significant threat to public-key cryptography, compromising encryption, digital identity, and software trust on a large scale. Quantum computing is transitioning from theoretical to practical applications, with far-reaching implications for data confidentiality and security. A key concern is the "harvest now, decrypt later" approach, where sensitive data is being collected now, to be decrypted later when quantum computers become capable of breaking current encryption methods1. This exposes long-lived sensitive data to potential future breaches, regardless of when these powerful computers become available. The risk is not limited to future quantum computer capabilities, but is already present, highlighting the need for proactive measures to mitigate potential damage. This development matters to security practitioners because staying informed about the evolving threat landscape is crucial for defending against emerging risks.
